In this exercise, you modify the bakery application from Chapter 3. Use Windows to copy the Bakery Solution folder from the VB2015\Chap03 folder to the VB2015\Chap04 folder, and then open the Bakery Solution (Bakery Solution.sln) file. When a text box in the interface receives the focus, its existing text should be selected. The Date text box should accept only numbers, the slash (/), the hyphen (-), and the Backspace key. The Doughnuts and Muffins boxes should accept only numbers and the Backspace key. Modify the code to reflect these changes. Test the application appropriately.
